$hash{'dimension', 'type'};

Yes, these exist and are equivalent to 

$hash{ join $;, qw( dimension type ) }

Not something you should use normally. Probably not even worth remembering, but you already did.

map{substr$_->[0],$_->[1]||0,1}[\*||{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^*ARGV,3]

    I remembered them because I have a bit of legacy code that produces them from an HTTP file upload...

    $file{$fileid, 'filename'};
$file{$fileid, 'content'};

    I don't use it for new stuff but there is quite a bit of existing code that still uses so I have to deal with it on occasion. I am guessing that's what I read that shouldn't be used now rather than multidimensional arrays.
